7.2 Charging and battery life
The battery is charged by connecting the external charger with the bulkhead connector on
the non-sensor end of the FDL Mini. A full charge will take about 5 hours.
The instrument will run for about 3 months at 25°C on a full charge. Battery life time
decreases with decreasing temperature and is about half at 4°C
7.3 Configuring the Field DataLogger Mini
It is important to
configure each channel of the FDL Mini before connecting the sensors
because the polarization must be set correctly and individually for each channel. Wrong
polarization may destroy the sensor. The correct polarization for each type of sensor is
found in the sensor manual.
Open the SensorTrace Logger software. The FDL Mini must be connected to the PC with the
supplied USB cable and the Off-dongle must not be connected.
Logger will now display the available channels. Channel 1 will always be temperature (read
from a sensor inside the pressure housing). If you have a 2-channel version channels 1 - 3
will be shown and if you have a 4-channel version channels 1 - 5 will be shown.
